New Language? New culture?

A new language was born on BBS. I think that the Japanese tends not to put out feelings to the table so much. On BBS, there is no face to face communication. But they want to convey their emotions to the other people

  • n BBS in their home.

It was led by the spread of the personal computer and the

  • Internet. So, they can communicate without face to face

communications using speech, facial expression and gesture.

Image analysis using YIQ systems

(1) original (2) I(YIQ) (3) extract only face (4) Face mask

(6) = (5)-(4)

(5) Y(YIQ)

The YIQ system is the color primary system adopted by National Television System Committee (NTSC) for color TV broadcasting. The YIQ color solid is made by a linear transformation of the RGB cube. Its purpose is to exploit certain characteristics of the human eye to maximize the utilization of a fixed bandwidth. The human visual system is more sensitive to changes in luminance than to changes in hue or saturation, and thus a wider bandwidth should be dedicated to luminance than to color information. Y is similar to perceived luminance, I and Q carry color information and some luminance information. The Y signal usually has 4.2 MHz bandwidth in a 525 line system. Originally, the I and Q had different bandwidths (1.5 and 0.6 MHz), but now they commonly have the same bandwidth of 1 MHz.
